CAR-COUPLING.

Specification of Letters Patent.

Patented June 5, 1217.

Application filed. February 16, 1917. Serial No. 148,964.

To all whom it may concern.

Be it known that I,-ANTON OLEJNICZAK, a subject of the Czar of Russia,resident of Chicago, county of nois, have invented certain new anduseful Improvements in Car-Couplings, of which the following is aspecification.

This invention relates to improvements in railway draw-bars, and has asits principal object the provision of means whereby a combined draw-barand bumper is cushioned with respect to its connection with a car, thecushioning elements being so arranged as to absorb the shock which wouldotherwise be imparted to the car body.

This and other like objects are attained by the novel construction andcombination of parts hereafter described and shown in the accompanyingdrawings, forming a material part of this specification, and in whichFigure 1 is a bottom plan view of a car frame showing the application ofthe invention.

Fig. 2 is a vertical sectional view taken on the center line of thesame.

' Fig. 3 is a bottom plan view of the same, some of the parts beingbroken away and others shown in section and Fig. 4 shows a detail ofconstruction.

The underside of the car body is represented by the numeral 10, and hasrigidly attached to it a longitudinally disposed strip 11, secured bymeans of transverse elements 12, which are also used to support thedraw-bar elements.

Coupling heads 14, of any approved design, are secured in thelongitudinal elements 11 at the ends by means of stems 15, which areslidably engaged in rigid plates 16, and formed at their inner ends withan largements 17 to which are secured casings 20 open at their sides,and slidable on fixed transverse bars 21 attached to the longitudinalelement 11. I

Interposed in the pockets formed by the casing upon either side of thecross bars 21, are rigid plates 22 having between them heavy coiledsprings 23, similar springs 24 being disposed between the correspondingplates 25, set in the pocket at the opposite.

side of the cross bars 21.

These springs are of suficient strength to withstand the tractive forcenecessary to draw the car, and at the same time to resist Cook, andState of Illior take up the thrust of an impulse communicated to thedraw-bar heads 14:.

In addition, in order to minimize the shock, a centrally disposed spring28 is contained in a bracket 29 secured midway of the car, the springsurrounding a portion of the enlarged bumper bars 30, connected by thestems 31 to heads 32, and held in slidable position by the brackets 33.

A similar head 35 is secured to the stem 36 slidable in the bracket 37,the opposite end of the stem being bifurcated and slidably engaged inthe bracket 12 and held therein by the center pin 38, the fork endsbeing engaged with heads 40 to which are secured pins 41, the samepassing through openings in the casings 20 and the contacting plates 25.

In operation, when one car or an engine is brought forcibly againstanother, the

draw-bar heads 14 are forced inward toward the center of the caropposing the springs 23 and by reason of the rigid casmg 20 part of thethrust is taken on the heads 40, transmitted through the elements 32 and35 and bar 81 to the spring 28, so as to absorb the shock and cushionthe action to a very considerable extent.

It will also be noticeable that should suficient energy be exercised bythe contacting car that the thrust effectwill be further transmittedthrough the springs 28 to the opposite end of the car and eventuallytaken up by the fixed bars 21, while the pull of the car is entirelytaken by the springs 24.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a combined draw-head and bumper, the combination with a rigidlongitudinal support attached to the car frame, drawheadsslidablyengaged at the ends of said support, casings connected to the inner endsof said draw-head, rigid cross-bars passing through said casing, springsdisposed upon either side of said cross-bar within said cas ing, aspring centrally arranged of said support element, said springbeing'adapted to operate in both directions, independent bars interposedbetween said springs, and means for supporting said bars.

In testimony whereof I have aflixed m signature this 5th day ofFebruary, 1917.
